    8 litres of \[{{H}_{2}}\]and 6 litres of \[\text{C}{{\text{l}}_{\text{2}}}\]are allowed to react to maximum possible extent. Find out the final volume of reaction mixture. Suppose P and T remains constant throughout the course of reaction.

    A)  7 litres                 

    B)  14 litres

    C)  2 litres                 

    D)  None of these

    Correct Answer: B

    Solution :

    \[{{H}_{2}}+C{{l}_{2}}\to 2\,HCl\] Volume before reaction \[8L\,\,\,6L\,\,\,0L\] Volume after reaction    \[2L\,\,\,0L\,\,\,12L\] Volume after reaction = Volume of \[{{H}_{2}}\]left + Volume of \[HCl\]formed \[=2+12=14\,L.\]
